The present disclosure provides a leg guard, which covers at least the calf of the user, preferably at least covers from the middle of the thigh to the ankle of the leg, which can not only provide warmth to the leg, but also provide it with stepped pressure, namely The pressure exerted by the leggings on the calf decreases stepwise from the thinnest point of the ankle circumference to the protuberance of the tibia below the knee.

The leg guard of the present disclosure can provide heat preservation and stepped pressure functions for the legs, effectively prevent low-temperature burns, varicose veins and venous thrombosis, and can also take into account the knee protection from wind and cold and the perspiration and ventilation of the knee socket, especially suitable for wheelchair users and unconscious legs person.

Embodiment one

As shown in Figure 1, this embodiment provides a leg guard 1, which is used to cover the user's lower leg from the top of the ankle joint to the bottom of the knee joint, and the pressure exerted on the lower leg decreases gradually from the top of the ankle joint to the bottom of the knee joint . This is conducive to promoting blood flow in the lower legs, and to a certain extent alleviates or prevents the occurrence of varicose veins. However, in some embodiments of the present disclosure, the leg guard can also achieve full coverage from the ankle O to the thigh F.

Specifically, the leg guard of this embodiment includes four pressure zones, respectively as follows:

(1) The first pressure zone A' is used to apply the first pressure to the thinnest point A (also known as the first pressure point) of the ankle circumference of the calf;

(2) The second pressure zone B' is used to apply a second pressure to the junction B between the Achilles tendon and calf muscle of the calf (also known as the second pressure point);

(3) The third pressure area C' is used to apply a third pressure to the calf circumference C (also known as the third pressure point) in the calf;

(4) The fourth pressure zone D' is used to apply a fourth pressure to the tibial protuberance D (also known as the fourth pressure point) below the knee of the calf.

Wherein, the pressure values of the first pressure, the second pressure, the third pressure and the fourth pressure decrease successively. As a more preferred embodiment, the ratio of the pressure values of the first pressure, the second pressure, the third pressure and the fourth pressure is 100:80:70:50.

In this embodiment, the specific pressure values of the four pressure zones are customized according to the specific conditions of the legs of different users, and there is no fixed value. The leggings of this embodiment are woven by hosiery machine equipment, and the pressure values can be adjusted differently by adjusting the tightness of the above-mentioned pressure zones during weaving. Specifically, different adjustments to the pressure value depend on the position of the motor and the position of the needle cylinder of the hosiery machine device during knitting. If the position of the needle cylinder is fixed, the higher the number of the motor, the greater the pressure and the density of the needle; if the position of the motor remains unchanged, the higher the position of the needle cylinder, the greater the density. The higher the density, the greater the stretch recovery rate of the product, and thus the greater the pressure value on the legs. After adjusting according to the actual situation of the equipment, the pressure value of the leg guards is measured after actually getting off the machine, and the product can be delivered if it meets the customer's requirements.

The trial-manufactured product involved in this embodiment has passed the stress test of the subjects. After the subjects wore leggings that matched their legs, the subjective feedback was that they could clearly feel the pressure from the ankle to the circumference of the thigh. Among them, the ankle is the tightest, and the pressure decreases from bottom to top. At the same time, the subjects who often used the wheelchair wore it for about ten minutes, and their pale legs showed a slight rosy phenomenon. The subjects believed that the stepped pressure and heat preservation function of the leg protectors also promoted blood flow in the legs.

The pressure value test of the above-mentioned four pressure zones of the present embodiment is tested with a flexible electrode electronic pressure sensor, and the circumference of four different pressure points on the calves of a large number of normal people and disabled people are tested respectively. These four pressure points are respectively : The smallest circumference of the ankle A, the transformation of the Achilles tendon and the calf muscle B, the largest circumference of the calf C, the prominence of the tibia below the knee D, and the middle of the thigh E. Each pressure point is located in a corresponding pressure zone, and the pressure value exerted by the corresponding pressure zone can be obtained by measuring the pressure value at the pressure point. For the circumference of each pressure point, 4 measurement points are taken at the front, back, left, and right, and 4 values are measured for each circumference, and then the average value is taken to represent the pressure value of this circumference.

According to the measured pressure data, combined with comfort experiments such as temperature and humidity, adjust the product's yarn fineness, fabric coil density, structure, girth and other process parameters, thereby adjusting the pressure value at each pressure point so that it can Form an effective pressure gradient and play a functional role in promoting blood circulation in the legs. At the same time, the content of each functional yarn is adjusted so that it can have a thermal insulation effect, so as to improve the comfort of the human body when worn.

According to the test results of normal people and leg disabled people, it is preferable to determine the pressure gradient of each pressure point of the leg guard and its corresponding pressure zone as the first pressure, the second pressure, the third pressure, and the fourth pressure, and the pressure value ratios are in order It is 100:80:70:50.

The leg guard of this embodiment provides a stepped pressure value on the calf from the thinnest ankle circumference of the calf to the tibial protuberance below the knee. The stepped pressure value has been tested and proven to promote blood circulation in the legs, prevent venous thrombosis or varicose veins in the legs, and relieve leg swelling, so it is especially suitable for sedentary people.

Embodiment two

Compared with Embodiment 1, the leg guard of this embodiment further includes: a fifth pressure zone E'. The fifth pressure zone E' covers the top of the knee joint of the thigh to the middle part of the thigh, and exerts a fifth pressure on the middle part E of the thigh (also called the fifth pressure point).

According to the test results of the normal person and the leg disabled person, it is preferable to adjust the pressure values of the fifth pressure and the fourth pressure to be equal.

For the pressure value test and pressure value adjustment method of the fifth pressure zone, refer to the description of the first embodiment.

Embodiment Three

Compared with the previous embodiments, the leg guard 1 of this embodiment further includes: a knee thickened area 2 . As shown in Figure 1, the knee thickening 2 covers the bottom to the top of the anterior knee joint.

The knee thickened area in this embodiment is consistent with the material of the leg guard body, including nylon, thermal storage yarn, and spandex. However, since the number of knitting stitches in the knee thickened area is greater than that of the rest of the leg guard, , which is thicker than the rest of the leggings.

The leggings of this embodiment are single-needle seamless knitting on a hosiery machine. In order to thicken the knees, keep warm and windproof, four-needle knitting is added to the front part of the knees, and the four yarns are directly knitted together with the body of the leggings with a hosiery machine. The increase in the number of yarns increases the thickness of the knees and the gap between the tissues. Less, to achieve the effect of keeping warm and windproof, the thickening size is about a circle with a radius of 10cm.

Because the knees of wheelchair users are most likely to catch cold when they are in a sitting position, increasing the thickness of the knee coverage area can prevent the knees from being exposed to the wind and catching cold. Thickening treatment has been carried out for other areas of the leg guard, therefore, the leg guard of this embodiment is conducive to the protection of the legs of handicapped people who often use wheelchairs.

Embodiment four

Compared with the third embodiment, the knee thickening area of this embodiment includes three layers, an outer layer, a middle interlayer and an inner layer.

Wherein, the material of the outer layer and the inner layer is the same as that of the rest of the leg guard.

The middle interlayer is made of windproof fabrics, such as: coated fabrics, laminated fabrics (such as e-PTFE laminated fabrics, Gore-Tex membrane fabrics, etc.), woven or knitted fabrics with high fabric density, etc.

Embodiment five

Compared with the third embodiment, the knee thickening area of this embodiment includes: the knee body and the windproof layer laid outside the knee body, the windproof layer is made of windproof fabric, such as: coated fabric, laminated Fabrics (such as e-PTFE laminated fabrics, Gore-Tex membrane fabrics, etc.), woven or knitted fabrics with high fabric density, etc.

Embodiment six

Compared with the third embodiment, the knee thickening area of this embodiment contains wool needle-punched components, that is, wool components are pricked on the body material of the knee thickening area by acupuncture technology, so as to play the role of windproof and warm-keeping.

Embodiment seven

Compared with the foregoing embodiments, the leg guard of this embodiment further includes: a knee cavity air-permeable area 2 . The knee fossa air-permeable area 2 covers the rear knee fossa, its thickness is smaller than that of the rest of the leg guard and it is ribbed.

The material of the knee pocket ventilation area 2 is consistent with the material of the body of the leggings, which is integrally woven with the body of the leggings using a hosiery machine, including three kinds of yarns: nylon, thermal storage yarn, and spandex. However, the tissue structure of the body material of the leg guard is 1×1 rib weave (as shown in FIG. 2 ), while the knee cavity air-permeable area 2 uses 2×2×2×2 rib weave (as shown in FIG. 3 ). Because the fineness of heat storage thermal yarn and spandex is finer than that of nylon, holes can be formed between tissues, thereby promoting heat dissipation on the skin surface of the back knee fossa and reducing sweat accumulation in the back knee fossa.

In a word, the leg guard of this embodiment corresponds to the knee fossa air-permeable area on the back knee fossa of the leg, which is light and breathable ribbed tissue; Sweat stimulates the skin of the back knee fossa; on the other hand, it reduces the creases of the leg guards at the back knee fossa, thereby improving wearing comfort.

Embodiment eight

Compared with the previous embodiments, the leggings of this embodiment are woven by composite weaving of 70wt% nylon yarn (70dtex×2), 10wt% spandex yarn (30dtex) and 20wt% heat storage yarn. The heat-storage yarn is full-spectrum heat-storage polyamide 6 fiber (77.8dtex, trade name of a commercially available product).

Nylon has good comprehensive properties, such as good mechanical properties, heat resistance, wear resistance, chemical resistance and self-lubricating properties. Its most prominent advantage is that its wear resistance is higher than that of other fibers, and it is more wear-resistant than cotton 10 times stronger than wool, 20 times stronger than wool. When nylon is added to the leggings, its wear resistance can be greatly improved. When stretched to 3-6%, the elastic recovery rate can reach 100%, and it can withstand tens of thousands of times of bending without breaking.

The thermal storage yarn is a full-spectrum heat-preserving functional yarn, which can efficiently store human body heat and reduce heat dissipation. The thermal storage yarns of the present disclosure contain full spectrum thermal storage filaments. The basic principle of full-spectrum heat storage filament is: the carbides of transition metals in group IV of the periodic table of elements are nano-sized and interface-treated, and then added to nylon fibers as additives, which can quickly absorb heat and have long-lasting heat preservation. Performance index of full-spectrum heat storage filament: Under the same direct sunlight conditions, the temperature rise comparison result with ordinary fibers: within 1 minute, the temperature difference is 5.6°C; within 10 minutes, the temperature difference is 10.9°C.

In short, the leggings of the present disclosure use full-spectrum heat storage yarns as weaving materials. The full-spectrum heat storage yarns can quickly absorb and store body heat and reduce heat dissipation, so that the temperature of the leggings is not much different from the body temperature of the legs, and no additional heating is required. It can keep warm without the low-temperature scald effect caused by self-heating leggings, and is especially suitable for people with no sense of leg.
